AVKit sample architecture
Source-backed, high-level architecture notes for Apple sample-code pages grouped in the AVKit folder.
- Catalog module label:
AVKit - Coverage: 6 / 6 sample pages documented
- Source policy: archive hashes and extracted-tree references are verified locally before analysis
Samples
| Sample | Platforms | High-level architecture | Documented patterns |
|---|---|---|---|
| Adopting Picture in Picture Playback in tvOS | iOS, iPadOS, Mac Catalyst, tvOS | A Swift sample with the source-visible chain AppDelegate → ViewController → AVKit APIs. |
View-controller organization, Protocol-oriented abstraction, Delegate or data-source callbacks |
| Creating a multiview video playback experience in visionOS | visionOS | A Swift sample with the source-visible chain MultiviewVideoPlaybackApp → ContentView → MultiviewStateModel → ItemVideoPlayer → AVKit APIs. |
Delegate or data-source callbacks, Binding-based state propagation |
| Playing immersive media with AVKit | visionOS | A Swift sample with the source-visible chain AVKitImmersivePlaybackApp → ContentView → PlayerModel → SceneProvider → AVKit APIs. |
Delegate or data-source callbacks |
| Playing video content in a standard user interface | iOS, iPadOS, Mac Catalyst | A Swift sample with the source-visible chain AppDelegate → PlaybackController → PlayerViewControllerCoordinator → AVKit APIs. |
View-controller organization, Protocol-oriented abstraction, Delegate or data-source callbacks, Coordinator |
| Supporting Continuity Camera in your tvOS app | tvOS | A Swift sample with the source-visible chain ContinuityCameraApp → ContentView → CaptureManager → CaptureDeviceNotificationObserver → AVFoundation / SwiftUI APIs. |
Delegate or data-source callbacks, Binding-based state propagation, Publisher-backed observable state |
| Working with Overlays and Parental Controls in tvOS | tvOS | A Swift sample with the source-visible chain AppDelegate → MenuViewController → AVKit APIs. |
